Hey, I created a Winform in VB.NET, and I added a Splitter control to allow resizing of panels during runtime. My issue is that the splitter control is not apparent. I would like to make it appear in a way that the user would know the form can be resized. At the moment, I basically just changed the color, but I don't like how that l...

The TextRenderer.DrawText method has a TextFormatFlags parameter. Using TextFormatFlags.EndEllipsis allows you to abbreviate the text with an ellipsis at the end so that it fits in the available space. However, I want to put the ellipsis at the start.

We're starting a new project and deciding to use Winforms or WPF. I've read some of the other SO posts, and realize that WPF has some advantages in the data-binding and appearance areas, but also has a steep learning curve and fairly immature tools and controls. We would like to better understand if Microsoft is planning on stopping ...

I have a form databound to a customer object, and one of the fields is a nullable int representing a "type". This is displayed as a combobox, and the combobox is bound to the "Types" table. When a customer with a null type is loaded into the form's datasource, the combo box displays no value, but then upon clicking it you must select a...
